Feature and Benefits

Efficiency class guarantee

The optimized electrical design and the material with low generation loss are used for core that make MITSUBISHI ELECTRIC AUTOMATION (THAILAND) guarantee “IE1” efficiency class on three phase motor.

Compatibility with distribution control devices

Since the motors are designed for combined use with Mitsubishi’s distribution control devices. The devices with equivalent specifications can be used for conventional motors.

Installation

Q-series models can completely replace the J-series. (Installation base according to IEC standard)

Compact Size and Light Weight

Size and weight reductions have been achieved by use of steel-plate frame and aluminium brackets in the small-capacity motors. Highly Reliable Insulation Systems
Class B and F insulation systems are characterized by superior resistance to heat, humidity and chemicals for top-notch reliability.

Full Lineup

We have produced variety types of motors, ranged from 1/4 HP to 10 HP, thus providing a full lineup of motors ideal for any application.

Superlative Characteristics and High Reliability

Based on experience and technology accumulated over many years, along with an exacting quality control system, each motor is ensured to exhibit only the finest characteristics.
Safety: All the rotating parts and the “live” areas are made sure that it cannot be accidentally touched directly.
Smooth Acceleration: The low moment of inertia of the rotor combined with the motor’s high acceleration torque, contributes to smooth starting and stopping.
Low Noise and Vibration Levels: This feature has been achieved due to our highly individualized electrical design, the ample rigidity and the precise machining of the motor frames and brackets, and the exact balancing of the rotor.
